+ * variant.cpp - Digital pin mapping for nRF52-based development board
+ *
+ * This file defines the pin mapping array that maps logical digital pins (D0-D17)
+ * to physical GPIO ports/pins on the Nordic nRF52 series microcontroller.
+ *
+ * Board: [Seeed Studio XIAO nRF52840 Sense (Seeed Solar Node)]
+ * Hardware Features:
+ *  - LoRa module (CS/SCK/MISO/MOSI control pins)
+ *  - GNSS module (TX/RX/Reset/Wakeup)
+ *  - User LEDs (D11-D12)
+ *  - User button (D13)
+ *  - Grove/NFC interface (D14-D15)
+ *  - Battery voltage monitoring (D16)
+ *
+ * Created [20250225]
+ * By [Dylan]
